Cell phone with light emitter and light receiver

Abstract

A cell phone having not only radio frequency (RF) emitter and RF receiver but also having light emitter and light receiver works together with an earphone having not only speaker and microphone but also having light emitter and light receiver. User will talk or listen with the earphone and cell phone will connect the system to the wireless communication network using RF signal. Communication between cell phone and earphone is carried out using light-wave in free space. By using light-wave based earphone to communicate with cell phone; users becomes less exposed to RF radiations.

Description

BACKGROUND[0001]4 billion people in the world own mobile phone and many of these cell phone users are children. Wireless cell phones transmit signals via radio frequency (RF), the same kind of low-frequency radiation used in microwave ovens and AM / FM radios. It is well-studied and proven that large doses of high-frequency radiation—the kind used in X-rays—causes cancer, but less is understood about the risks of low-frequency radiation. Studies on the health risks of cell-phone use have produced mixed results, but scientists and medical experts warn that people should not assume no risk exists.[0002]Because cell phones haven't been around very long, scientists haven't been able to assess the effects of long-term cell-phone use, or to study the effects of low-frequency radiation on growing children. Most studies have focused on people who have been using cell phones for three to five years, but some studies have indicated that using a cell phone an hour a day for 10 years or more can ...

AI Technical Summary

Benefits of technology

The invention is about a special earphone for cell phone users that reduces the amount of RF radiation that they are exposed to. The technical effect is to protect the user's health from excessive RF radiation while using the cell phone.

Problems solved by technology

It is well-studied and proven that large doses of high-frequency radiation—the kind used in X-rays—causes cancer, but less is understood about the risks of low-frequency radiation.

Because cell phones haven't been around very long, scientists haven't been able to assess the effects of long-term cell-phone use, or to study the effects of low-frequency radiation on growing children.

Most studies have focused on people who have been using cell phones for three to five years, but some studies have indicated that using a cell phone an hour a day for 10 years or more can significantly increase the risk of developing a rare brain tumor.

But it is not convenient to use conventional earphone since the earphone has to connect to cell phone with a wire.
